Information Acquisition from a Specific Number of Nodes with Designated Attributes in DTN Environments

With the advancement of the information society, the importance of acquiring and utilizing various types of information from specific users with designated attributes has been increasing. This paper proposes an information acquisition method that leverages the data forwarding capability of delay tolerant network (DTN) to collect such information with mobile devices in a shorter time, without causing data transfer loads and costs on the fixed communication infrastructure. Its effectiveness is shown through computer simulation.
